What matters should we pay attention to when applying polyurethane material to the automatic dispenser of wall washing lamp? 1. Before gluing, the super glue should be vacuum packed to remove bubbles. If it is not vacuum packed, bubbles will appear when it is poured out. 2. Polyurethane glue a is a kind of epoxy curing agent, which is easy to form crystal in case of moisture in the body. 3. If it is grayish black or light yellow strong adhesive, then B adhesive has filler and needs to be mixed. If it is transparent glue, there is no need to add mixing. 4. Polyurethane glue is very easy to react with water vapor, and the moisture in the body forms many bubbles, so the surface of the wall lamp should be dry.
LED light strip for wall washing lamp: the LED light strip is composed of solar cell, LED lamp bead and resistor. The three parts are made up of semi-finished LED light strip. The thickness and high thermal conductivity of solar cells are beneficial to the heat removal of integrated IC. Generally, OSRAM 3030 smded lamp beads are selected as lamp sources. Led wall washing lamp structure lamp arm: the shell is made of high-quality 6063 aluminum alloy profile and toughened laminated glass.
Basically, the larger the output power of the wall washing lamp is, the thicker the shell is and the larger the specification is, so the better the actual heat removal effect is. In addition to heat removal, the lamp arm of the wall washing lamp also has another key function, that is, to maintain the lamp source PCB circuit board inside the lamp arm, and to reasonably deal with the waterproof problem.
With the increasing demand of LED wall washing lamp manufacturers, the sales market has been in a fight. Now the quality is uneven. If you buy the poor quality, it will be a disaster. Small and medium-sized wall washing lamp manufacturers produce wall washing lamps, which are more cost-effective. It is based on reducing the quality of products. They choose fake and inferior lamp sources. Because the light intensity of fake and inferior lamp sources is not enough, they generally increase the LED color temperature according to the way, that is, cold milky white.
Achieve the effect of high brightness for consumers. Cold milky white LED color temperature is too high, it is very easy to cause irreversible damage to the eyes, it is not suitable for application. In addition to the fake and inferior light source, the poor quality of the selected cable and lamp arm can easily lead to problems such as poor contact, and even problems such as power loss. Don't just try to be cheap for a while, the damage that will bring you is in all aspects and endless.
